The screen in the car is completely blank with no menu items. I tried inserting a software upgrade disk that I have used successfully in the past (v.28) but the same thing happens and it does not install. When these units leave the factory is the software pre-installed? Is there anything else I can try to get it up and running? Thanks in advance for your help. I hope I don't own a paperweight.
